Abstract

A simple and straightforward method to objectively measure the transverse chromatic aberration (TCA) at horizontal field angles out to ±10° from the visual axis of the human eye was proposed. Longitudinal chromatic aberration (LCA) was also measured across the visual field. The TCA of a human eye was obtained by deviation of the point spread function (PSF) images. LCA was calculated from the Zernike defocus. The average TCA changing with eccentricity was 0.162 arcmin/degree between 639 nm and 795 nm wavelengths. Near the optic axis of the eye, the average LCA was 0.37 ± 0.02 D, and it increased slightly with eccentricity (up to 0.54 ± 0.02 D).
